Counting Efficiency for Rapid Preparation of Known Amounts of ^<222>Rn by the Air Luminescence Method
The counting efficiency for air luminescence due to <SUP>222</SUP>Rn and its daughters was determined with commercially available liquid scintillation spectrometers giving much attention to Cherenkov radiation due to β<SUP>-</SUP>-particles and internal conversion electrons from <SUP>214</SUP>Ph and <SUP>214</SUP>Bi. Based on the results, we propose a rapid and reliable method for preparation of known amounts of <SUP>222</SUP>Rn, which are needed for calibration of detectors measuring <SUP>222</SUP>Rn or a number of experiments using <SUP>222</SUP>Rn, without elaborate instrumentation or technique.
